How long does GEO take to show results?

GEO involves three layers of work, and each shows up on its own timescale: access fixes in days to weeks, new pages and consistent naming in weeks to a quarter, independent brand coverage over quarters. Most disappointment with a GEO results timeline comes from expecting the slowest layer to move at the speed of the fastest.

Two terms first, because the rest of this guide uses them. Citation rate is the share of your prompt set where an assistant links to one of your pages. Share of voice is your share of all brand mentions across that same prompt set, measured against the competitors who appear next to you.

First, check whether crawlers can reach your pages at all. Next, publish one page per specific buyer question and keep the company’s name and description identical everywhere. Third, build recognition through independent sources that name the brand. Our checklist for when AI visibility has not improved walks the same three layers in the order you would debug them.

The table below gives each layer with the earliest signal you can check without us and the only published figures we know of. Before it, our own dated points, so the horizons are anchored to things that happened rather than to a promise. Each is one assistant on one day unless it says otherwise.

For the access layer, the only published number belongs to OpenAI: after you change robots.txt, it takes about 24 hours for their systems to adjust. That covers permission, not content. No vendor publishes how quickly a crawler returns to a page whose text changed, so treat “days” as our observation from logs rather than a documented rule. If you want the per-agent file to paste, our robots.txt guide for AI crawlers has it.

For the content layer, Google states that a requested recrawl takes anywhere from a few days to a few weeks. AI Overviews and AI Mode draw on that index, which makes it the closest published figure to “when will a new page start appearing in AI answers”. The two numbers measure different things, policy propagation versus recrawl and reindexing, so neither ranks one assistant as faster than another; the FAQ below explains why we refuse to make that comparison.

There is no published timetable for independent brand coverage. We count the domains mentioning the business at the start and again each quarter. If the number has not changed after two quarters while other measures improve, further website edits alone are unlikely to secure recommendations for broad questions. That is the layer where a date cannot be promised at all, which is why our guide on what a GEO guarantee can honestly say ties any promise to the prompt set and the baseline, never to the calendar.

get-geo.ai went live in June 2026 with most of the technical layer in place: server rendering, hreflang across eight languages, structured data, llms.txt. One thing we had missed. On August 4 an audit of our own site found a redirect loop between the bare domain and www. Google’s crawler survives that loop; AI fetchers, which often give up after one or two requests, frequently do not. We fixed it the same day; the write-up of that audit shows the curl output before and after.

Nine days later, on August 13, five clean ChatGPT sessions asked for a GEO agency for a company working in several languages, phrasing varied between runs. It named get-geo.ai in five out of five; a sixth run on August 17, English plus Spanish, did the same. Launch to first reproducible citations on those prompts: about two months. Six runs across two days is not proof of stability, and our case study says so in its own limitations. The prompts also matched our services closely: an agency that lists its languages is a natural candidate for a multilingual brief.

The second point is a remeasure. On September 3 we ran four Hindi-agency prompts once each and were absent from one. On September 15, twelve days later, the same four prompts twice each: 8 of 8, first in 6, and #4–5 on the prompt we had lost. The Hindi case keeps both tables side by side. What the assistant picked up was not one page but the entity: it cited the home page, the case page and two guides interchangeably.

The third point is the fastest and the one we are most careful with. Our guide on what happens if GEO does not work after 90 days went live on September 14; on September 15 Perplexity and Google’s AI Mode both cited it, on the one prompt the page answers in its title, AI Mode in both repeats. Across three assistants that weekend, every citation of get-geo.ai came on the two prompts about the 90-day policy and guarantees, the prompts where a page of ours states a checkable commitment. A page answering a narrow question can be picked up in a day; broad recommendations in a crowded category take longer. Plan in that order.

Generated answers vary between runs. In our five August runs of one prompt family, twelve different competitors appeared alongside us; our position held, the field around us did not. In the Hindi remeasure, two runs of the same prompt on the same morning produced different competitor lists. A single run says nothing about a date, which is why we measure a fixed prompt set every two to four weeks and report movement in citation rate and share of voice, and why a promise of “cited within N days” belongs on the list in our guide to GEO agency red flags.

Freshness keeps mattering after you arrive. Of ChatGPT’s 1,000 most-cited pages in Ahrefs’ analysis, 564 had a detectable update date; among those, 76.4% had been updated within the previous month and 8.9% were older than a year. More than half of that subset is Wikipedia, and Ahrefs warns that the update timestamps are unreliable, so read it as a correlation between fresh pages and citations, not as a decay curve for your page.

The verification step adds variance of its own. OpenAI’s help page on searching the web says ChatGPT typically rewrites a question into one or more targeted queries, may send further, more specific queries after reading the first results, and ranks what comes back “using multiple factors”, with placement not guaranteed. Which page those searches return can differ from run to run, and so can the answer. The honest form of a guarantee is therefore a formula about the prompt set at day 90, not a date, and our guide on GEO guarantees writes that formula out.

We start each part of the work early enough to allow time for its effects to be measured. If you are buying this from an agency, the same dates belong in the agreement: our GEO contract checklist shows what the results, exit and data clauses should say.

Citations move last. Three signals arrive earlier, one per layer, and each has a date by which its absence stops being normal.

Access layer: AI crawler hits in server logs. OAI-SearchBot, PerplexityBot and Claude-SearchBot appearing on the new pages, and returning, means access is fixed. Google-Extended is a robots.txt token rather than a user-agent, so look for Googlebot instead. If none of them has fetched a page several weeks after publication, the access work is not done, whatever the rest of the plan says.

Content layer: refetches of pages you changed. A crawler returning to a page shortly after you update it is the mechanism behind the freshness correlation above, and logs show it long before an answer does.

Commercial layer: assistant referrals in analytics. Sessions from chatgpt.com, perplexity.ai and gemini.google.com are the outcome you are actually buying, and they usually start as a trickle on one or two pages before the prompt set shows a visible shift. When the trickle and the prompt set agree, the movement is real.

Warning signs by date. Each one is a threshold from the figures above, not a forecast; when you hit one, the layer named is where to look, and our checklist for AI visibility that has not improved has the commands to run.
